Bi-Directional Amplifiers

Fairview’s bi-directional amplifier models are designed for use in both commercial and military applications and will support any signal type and modulation format such as 3G and 4G telecom, WLAN, OFDM, DVB and CW/AM/FM. Fairview’s bi-directional amplifiers offer high power density, efficiency and linearity in small lightweight environmentally sealed packages with SMA connectors. These units also feature a quick-connect circular locking connector for DC and control functions and each design uses a single voltage supply with voltage regulation.

Our bi-directional RF amplifier line consists of two narrow-band models that operate in L-Band from 1.35 to 1.39 GHz and S-Band from 2.4 to 2.5 GHz. Also available is a “general purpose” broadband model that covers 30 MHz to 3 GHz. These designs produce high quality transmit signals across 802.11 wireless networks while amplifying received signals with low noise figure of 2.5 dB to produce the highest possible data rates. Typical transmit gain levels for these amplifiers range from 20 to 23 dB with ±0.5 dB gain flatness. Another key feature is fast switching capability (1 microsecond typical) between Transmit (Tx) and Receive (Rx) states.
